A remarkably disjunct population of Valerianella multidentata (Caprifoliaceae) in the south of Spain

Abstract

We provided the first record of Valerianella multidentata Loscos & Pardo for the flora of Andalusia (south of Spain). The specimen was collected during fieldwork in the southwest of Cordoba province. This new population illustrates a remarkable expansion of the species' geographic range very disjunct from its northeastern distribution core. The main morphological differences of the achenes between Valerianella multidentata and its relatives (V. coronata and V. discoidea) are provided. A geographical distribution map and detailed pictures of the specimen are also presented.
